Abstract: A display panel includes a first substrate, pixel structures, a first common pad, a second substrate, a second common electrode, a display medium and a conductive particle. The pixel structures are disposed on an active area of the first substrate. The first common pad is disposed on a peripheral area of the first substrate, and is electrically connected to first common electrodes of the pixel structures. The second common electrode is disposed on the second substrate. The conductive particle is disposed on the first common pad, and is electrically connected to the first common pad and the second common electrode. The conductive particle includes a core and a conductive film disposed on a surface of the core, where the conductive film has a main portion and raised portions, and a film thickness of each of the raised portions is greater than a film thickness of the main portion.

Abstract: A front wheel stabilizing device includes a mount adapted to be secured to a main frame of an electric motor-driven wheeled vehicle, and an axle disposed between two side plates of the mount. A wheel mounting member has a tubular head which is rotatably sleeved on the axle, and a cantilever arm which extends from the tubular head forwardly to terminate at a wheel-carrying end for mounting a stabilizing wheel thereon. The stabilizing wheel can yield under a jolting force that arises as a result of movement of the stabilizing wheel over an uneven ground so as to displace from a more tractive position to a less tractive position. A torsion spring has a coiled segment which is wound on the tubular head, and two urging ends which abut against the mount and the cantilever arm, respectively, so as to bias the stabilizing wheel downwardly, thereby restoring the stabilizing wheel from the less tractive position back to the more tractive position.

Abstract: A wheelchair includes an anti-wobbling roller mounted at a front portion of a seat frame and spanning across a center of the front portion in such a manner that the roller is capable of balancing the wheelchair in case the roller collides with an obstacle during forward movement of the wheelchair.

Abstract: A wheeled chair includes a wheeled frame having an upright post that defines a vertical axis, a seat mounted rotatably on the upright post so as to be turnable relative to the wheeled frame about the vertical axis, and a seat locking unit including a retaining member secured to the upright post and formed with a plurality of retaining grooves, a mounting seat secured to the seat, and a spring-biased tongue member disposed above the retaining grooves, mounted movably on the mounting seat, and operable so as to be moved between a locking position, in which, the tongue member is moved downwardly to selectively engage one of the retaining grooves so as to prevent turning of the seat relative to the wheeled frame, and an unlocking position, in which, the tongue member is moved upwardly to disengage from the selected one of the retaining grooves so as to permit turning of the seat relative to the wheeled frame.

Abstract: An armrest assembly for a wheelchair which includes a seat, two support braces, two front legs, and two rear legs. The armrest assembly includes at least one box placed on an associated support brace. At least one fastener is secured to a front end of an associated support brace. At least one first tube has an upper end fixedly mounted on a front end portion of the box and a lower end detachably engaged with the fastener. At least one second tube has an upper end fixedly mounted to a rear end portion of the box and a lower end pivotally engaged with an associated rear leg. At least one pivot base is secured to the front end portion of the box. At least one pivot block is pivotally mounted on the pivot base. At least one pivot arm is pivotally engaged with an extension of the pivot block and is releasably mounted in a chamber of the box. At least one holding table is fixedly mounted on the pivot arm and is releasably received in the chamber.
